Counter-rotating vortices in miscible two-component Bose-Einstein condensates
Shungo Ishino, Makoto Tsubota, Hiromitsu Takeuchi
Counter-rotating vortices in miscible two-component Bose-Einstein condensates, in which superflows counter-rotate between the two components around the overlapped vortex cores, are…
Countersuperflow instability in miscible two-component Bose-Einstein condensates
Shungo Ishino, Makoto Tsubota, Hiromitsu Takeuchi
We study theoretically the instability of countersuperflow, i.e., two counterpropagating miscible superflows, in uniform two-component Bose-Einstein condensates. Countersuperflow i…
Binary Quantum Turbulence Arising from Countersuperflow Instability in Two-Component Bose-Einstein Condensates
Hiromitsu Takeuchi, Shungo Ishino, Makoto Tsubota
We theoretically study the development of quantum turbulence from two counter-propagating superfluids of miscible Bose-Einstein condensates by numerically solving the coupled Gross…
Counterflow Quantum Turbulence and the Instability in Two-component Bose-Einstein Condensates
Shungo Ishino, Hiromitsu Takeuchi, Makoto Tsubota
We theoretically study the nonlinear dynamics of the instability of counter-superflow in two miscible Bose-Einstein condensates. The condensates become unstable when the relative v…
Two-superfluid Model of Two-component Bose-Einstein Condensates; First Sound and Second Sound
Shungo. Ishino, Hiromitsu Takeuchi, Makoto. Tsubota
Superfluid He at a finite temperature is described by the two-fluid model with the normal fluid component and the superfluid component.We formulate the two-fluid model for two-…
